It’s important to allow only limited resources because many intelligence tasks become easy with unlimited computation. We focus on precisely specified problems such as proving theorems, writing programs, or designing faster computer hardware. Many less precise tasks, such as creating humor, poetry, or art, can be fit into this framework by specifying their desired effects, eg. “Tell a story that makes Fred laugh.” Philosophical aspects of mind like qualia or consciousness are fascinating but will not play a role in the discussion.
